The Kano Pillars are a framework used in product development and customer satisfaction. They categorize customer preferences into five distinct types: Basic Needs, Performance Needs, Excitement Needs, Indifferent Needs, and Reverse Needs. This helps businesses understand what features are essential, what enhances satisfaction, and what may even detract from it. By analyzing these categories, companies can prioritize their efforts in product design and improvement. For instance, meeting Basic Needs is crucial to avoid customer dissatisfaction, while focusing on Performance and Excitement Needs can lead to increased customer loyalty. This approach is often associated with the work of Noriaki Kano, a Japanese professor who developed this model in the 1980s.
